hmmm, if they are rare, they are worth more than their weight in gold and should be sold to some collector who would keep them intact.

Otherwise, there are many places in the U.S. that buy gold. You may not get the highest price from any of those tv ads though. There are more reputable firms like
APMEX, KitCo, J&W and I'm sure google would list many more.
Then there's
ebay... and there's no tellin' who/where they would end up

. But, in the case of
ebay, pretty much any gold item will sell fairly, when sold with a reputable jeweller's assay... a document guaranteeing an item's weight and purity, with no regard to numismatic(coin collectability) value.
You best bet for a quick sale would be to get the assay. I am not really a medal collector, so I don't know if there are companies that would grade these as coins can be graded... which garantees their authenticity. You said you had it (acid)tested. Did you get a document of this test? It may be all you need... incidentally, it would give me bad vibes selling/buying an unknown/unmarked without some sort of third party guarantee.
I do have a few medals, and I know exactly what I'm getting into before I commit. Go ahead and put up some pictures... there are alotta very knowledgeable folks here who would be happy to at least take a look... and perhaps trounce me for daring to tell you where to sell them for melt!
